Running pytest from commandline works and the code is executed.
However, if I run handler_test.py directly, I receive an error:
Traceback (most recent call last):
File ".../tests/handler_test.py", line 5, in <module>
from libs.handler import ConfigurationHandler
ModuleNotFoundError: No module named 'libs'
handler_test.py
import pytest

#some test cases
I added pytest as a pre-commit hook, which will execute all tests. However, running pytest to test a single test file is a bit overkill. Having the opportunity to execute test files would be great.

Other people have run this code fine, and according to this question (and this one), my structure is good and I am not missing any files. I can only conclude that something about my computer or project set-up is not right. If you have any suggestions or insights that I may be missing, please send them my way!

I have docker as well as running pytest outside of docker too, and for me a much lower-impact fix whenever this crops up is to delete all the compiled python files
find . -name \*.pyc -delete
I figured it out and I'll answer in case others have the same issue:
I didn't even take into consideration that I had a docker container (of the same app) in the repo directory and, although I was not running the docker container, it was influencing the filepaths somehow.
To fix this:
I re-cloned the repo from the remote source into a new folder so that nothing from the old repo could "contaminate" it.
Updated my virtual environment with the .yml specifications of the clean repo
$ conda env update --name project --file project.yml
My project uses a postgres database, so I dropped it and created a new one
$ dropdb projectdb
$ createdb projectdb
Since my project uses mongo, I also dropped that database
$ mongo projectdb --eval "db.dropDatabase()"
Installed a clean pytest
$ pip uninstall pytest
$ pip install pytest
...and voilà! I could run pytest.
Many thanks to #hoefling and others who helped me debug.
I was running docker as well, but it seems my problem was different.
I was using an old version of pytest:
platform linux -- Python 3.9.7, pytest-3.7.2, py-1.10.0, pluggy-1.0.0
which stopped working after my ubuntu image was pulling python 3.10 by default.
my solution was to update (and fix) the dockerfile image to use:
FROM python:3.10
instead of python:latest, and update the pytest version as well.
I'm getting the following error when trying to run psycopg2 in a AWS Lambda:

The weird thing is: everything was working fine until yesterday (for more than 5 months), and suddenly stopped working. None of the libraries has been updated.
I tried to build from scratch, as in https://github.com/jkehler/awslambda-psycopg2, but still having the same error.
Can someone help me with it?
The problem is in the latest version of serverless framework. I assume that you are using serverless to deploy your lambda function.
serverless remove
npm install serverless#1.20.2 -g
This should work.
I got this estructure, that works in eclipse, but I got a import error in cmd. I tried sys.append.path but it does not works.
I´m running main.py
python main.py
In eclipse running the same code, ctrl+f11, it works fine.
Principal\__init__.py
Principal\lib\_init__.py
Principal\lib\functions.py
Principal\App_user\__init__.py
Principal\App_user\main.py
Principal\App_user\controller\__init__.py
Principal\App_user\controller\User_Controller.py
I got in User_Controller.py, from Principal.lib import funcionesDB it works in eclipse but it doesn't in cmd.
Traceback (most recent call last):
File "main.py", line 175, in <module>

you may need to change you directory to where you code is, and then run it in cmd line like: python main.py, or you may need to specify the directory of your code just like: python "path of code"/print_test.py.
After installing pyql from the package source(according to its own wizard described in this file) on Ubuntu 14.04 into /usr/local/lib/python2.7/dist-packages/ folder, all tests finished with success. This folder includes all additional installed packages, which are accessible, from the python using native import command.
But, this specific installation python don’t see, and I cannot import anything from it.
Have you any idea, what I need to define in addition?
Thanks,
Yigal B.
There are results of my sys.path:

print(sys.path)

Can you post the content of you sys.path? And the output of
python -c 'from quantlib.settings import __quantlib_version__; print __quantlib_version__'
I'm using the execnet package to allow communication between Python scripts interpreted by different Python interpreters.
The following code (test_execnet.py):
import execnet
for python_version in ('python', 'python3'):
try:
gw = execnet.makegateway("popen//python="+python_version)
ch = gw.remote_exec('channel.send(1/3)')
res = ch.receive()
print(python_version, ': ', res, sep ="")
except:
print('problems with ', python_version)
Runs perfectly in the command-line Terminal, showing the following output:
$ python3 test_execnet.py
python: 0
python3: 0.333333333333
However, if I try to run the same code from within the Eclipse IDE, I get the following error:
'import site' failed; use -v for traceback
Traceback (most recent call last):

NOTE:
Eclipse Version: 3.6.0

"Preferences/Interpreter - Python"'s Python Interpreters:
python (/usr/bin/python)
python3 (/Library/Frameworks/Python.Framework/Versions/3.1/Resources/Python.app/Contents/MacOS/Python
EDIT:
I write a code to show the os.environ like this:
for python_version in ('python', 'python3'):
try:
import os
for item in os.environ:
print(item, '= ', os.environ[item])
except:
print('problems with ', python_version)
I got the following outputs:
eclipse_output.txt
terminal_output.txt
A FileMerge comparison of the files can be found at eclipse_output.txt vs. terminal_output.pdf.
Any hints?
Thanks
seems like pydev does site-customizations and particularly modifies things for interactive/console usage (judging from a very quick skim of http://github.com/aptana/Pydev/blob/master/plugins/org.python.pydev/pysrc/pydev_sitecustomize/sitecustomize.py ). This is not useful or fitting for execnet-mediated processes.
You could try to "del os.environ['PYTHONPATH']" before you invoke execnet.makegateway, or, to be more careful, just delete the sitecustomize part of it.
hth,

I have seen that when python was unable to find its landmark. Which that indicates there is a PYTHONHOME problem.
Check out http://docs.python.org/using/cmdline.html#envvar-PYTHONHOME maybe eclipse is screwing your environment up.
Edit:
Looked at your env dumps, looks like eclipse is definitely messing with PYTHONPATH, which will cause your child python processes to not work correctly.
Basically what you have going on here is eclipse starts a python v2 instance with a PYTHONPATH pointing to the python v2 directories. Then you spawn a python v3 process which tries to load its landmark from the python v2 directories...
You need to find a way to have eclipse not mess with the PYTHONPATH. I am not sure what eclipse is trying to do by doing that, but it is certainly no friend when you want to spawn new python processes.
